Application February 9, 1938.. Serial No. 1:9,050

Renewed July 20, 1938 This invention relates to certain improvements in flushing apparatus for water closets, and partlcularly to the low down tank type, wherein the functioning of the flush tank is controlled by the operation of a float valve and the tank is mounted closely adjacent the closet bowl.

The object of the present invention is to provide a combination of closet bowl and flush tank of the type indicated, whereby the tank can be secured directly to the bowl without requiring intermediate piping or cou hugs, and at the same time provide a direct communication between the tank and the inlet chamber or flushing rim of the closet bowl.

A further object of the invention is the provision of a novel construction of flush tank in which all metallic parts have been eliminated and thereby materially reducing the cost of manufacture and installation.

Another object of the invention resides in the production of a flush tank in which the overflow is formed as a part, or continuation of, a discharge chamber, all of said parts being formed as an integral part of the tank.

Another object of the invention is to provide a valve seat or opening between the outlet chamber of the tank and the tank proper, said valve seat being integrally'formed in the upper wall of said chamber to the elimination of the usual metallic valve seat.

A still further object is to provide a support for the guide for the valve stem, also as an integral part of the flush tank, said valve guide support projecting inwardly from the front wall 35 of the tank as shown.

Another object of the invention is to construct the rear of the closet bowl with an inlet chamher and at the same time provide a' horizontal or vertical flat surface to receive and closely support the bottom portion of the flush tank, said tank being secured thereto by bolts or the like and a direct communication established between the outlet chamber of the tank and the inlet chamber of said bowl with a water tight seal 45 provided between the parts adjacent said communication.

In the usual, or conventional flush tank constructions, the overflow, outlet valve seat, and valve stem guide, are generally formed of metals 50 as an assembled unit and mounted inside the tank. Necessarily being of non-corroding metal these parts add considerably to the expense of manufacture as well as to the time and labor of installation. Furthermore, where the tank is made of vitreous ware, the tank manufacturer has to obtain these metallic parts from other manufacturers, all of which adds materially to the final cost of the fixture.

In addition, by the combination construction as shown, with the tank secured directly to the '5 closet bowl and with the inlet and outlet openings also in direct communication. all piping or metallic couplings-have been removed, which further simplifies the construction and assembly of the parts and obviously reduces the cost of pro- 19 duction.

The preferred embodiment of the invention is illustrated in the accompanying drawings in which.

7 Figure 1 is a side elevational view partly in section, illustrating the preferred form of applicant's combination fixture.

Figure 2 is a fragmentary view, partly in plan and partly in section on line 2-4 of Figure 1.

Figure 3 is a fragmentary plan view of the rear portion of the closet bowl with the tank removed, taken on line 3-4 of Figure 1.

Figure 4 illustrates amodifled arrangement of flush tank and closet combination and Figure 5 is a view taken on line H of Fisas ure Referring to the drawings in detail the improved combination fixture comprises a closetbowl I directly supporting a flush tank 2. the parts being rigidly secured together in the manso ner to [be hereinafter described.

With particular reference to Figures 1, 2 and 3, the rear of the closet bowl I is provided with a relatively flat shelf comprising an inlet chamber land horizontal side extensions] and I, the inlet chamber communicating with the flushing rim 6 of the bowl I as shown.

The flush tank 2 is secur to the extensions l and 5 by bolts or the like I and l passing through the bottom of the tank and openings or holes 9 and I0 formed in the extensions 4 and I respectively. These extensions 4 and 5 are also provided with openings II and I! for securing thereto the closet seat (not shown).

Immediately above the inlet chamber 3 of the closet bowl I and communicating therewith, there is provided in the aforementioned rear shelf of said bowl, an inlet opening II which is in turn in direct communication with the outlet opening ll of the flush tank 2 when said tank is in operao tive position. Surrounding the outlet opening II, the rear shelf of the closet bowl is formed with an annular recess II adapted to receive a packing or sealing ring I or similar gasket, providing the necessary water tight ioint between 5 the shelf and bottom ofthe flush tank at this point.

' Directly communicating with the outlet opening ll of the flush tank 2, and within said tank, is

5 an outlet chamber I1, extending across the bottom of the tank and connecting with an overflow conduit l8 extending upwardly adjacent one of the side walls of the tank and preferably the rear wall as shown in Figures 1 and 2. This over- 1o fiow I8, is preferably a continuation of the outlet chamber l1 and both the chamber and conduit are formed as an integral part of the tank 2 and of the same material as said tank.

Above the inlet and outlet openings "and I4 respectively, and preferably in line therewith, the top wall'of the outlet chamber I1 is provided with a circular opening IS, the edges of said opening being beveled to provide a seat for a .spherical or'semi-spherical float valve 20, said flat valve seating directly in the opening and thereby eliminating the conventional metallic valve seat usually provided in these structures.

The valve stem 2| extends upwardly through an opening 22 provided in an inwardly projecting removable and adjustable guide member 23,whereby the float valve is maintained in operative relation with respect to the valve seat I 9 and properly guided in its upward and downward movements. This valve stem guide 23 is adjustably secured to a boss or projection 23', formed as an integral part of the flush tank 2.

In the modification as shown in Figures 4 and 5, the bottom of the flush tank 2 is constructed with a downwardly projecting intermediate portion 2| forming an outlet chamber 25 having an outlet opening 26 provided in a substantial fiat vertical flange 21, said opening 26 adapted to register with the inlet opening 28 in the rear portion of the closet bowl also of modified construc- 0 tion as illustrated in Figure 4. The flange 21 is provided with upper side openings 29 and 30 and a lower recess 3| to receive bolts or the like 32, 33 and 34, respectively, whereby the tank is securely fastened to the rear of the closet bowl I,

a gasket or the like 35 being provided to seal the joint between these parts.

It is of course to be understood that the boss or projection 23' could be positioned directly above the opening l9 and the valve stem guide opening 22 formed'directly in said boss, but the construction and arrangement as shown is preferred as it allows for the insertion and operation of the necessary tool to grind the valve seat at opening l9.

Obviously other modifications of thesame gen- .eral idea could be devised involving the inventive thought as disclosed in the instant application and it is to be understood the present invention is to be limited only so far as defined in the ap- 30 pended claims.
